Siphonophores are gelatinous stings that clone themselves multiple times. The cloned structure works as an organ and all cloned parts work together as a team. All cloned structures stay together and this critter keeps increasing in size. There are approximately 180 species of Siphonophores. Man O' War is probably the deadliest variety.
